VACCINE-CARRIER AND CASE.

SPECIFICATION forming part of Letters Patent No. 634,709, dated October 10, 1899.

Application filed August 15,1899; Serial No. 727,336. on model.)

sible the lymph from absorption and from the injurious effects of the atmosphere and in so doing to provide .for the loaded or charged point of the carrier a simple and effective case or protectin'g-shelland one which is adapted for use with individual vaccine-carriers.

In a prior'patent, No. 616,642, granted to me December 13 1898, I have described and claimed a vaccine-carrier case having a protecting case or shell of paraffin or other mate rial which isnon absorbent and non-destructive' of glycerinized vaccine-lymph, into which the chargedpointof the carrier is sealed. My present invention is an improvement upon said patented invention.

Under my present improvement the case or shell for the vaccine-carrier is compos'edof a strip of paraffi n-coate'd pliable material which is doubled or folded on itself, paraflin face inward, and has between its meeting faces a of the carrier, which is sealed into said pocket,

pocket to receive the vaccine-charged point the paraffin coat thus'becoming the lining of the shell. Such a case or shell, while it may be used to contain more than one carrier and for that purpose may be provided with more -than one pocket, is particularly adapted to be used in connection with. a single carrier,

and it is for that purpose that it has been .moreespecially designed.

In lieu of paraffin I may use stearin or'wax or other'snitable material which is non-absorbent and non-destructive of glycerinized vaccine-lymph, and I desire to be understood, as including any such modification in my claim.

To enable others skilled in the art to make point of the carrier.

line2 2, Fig. 1, of the completed article. Figs. 3 to 6;inclnsive, are views illustrative of the 'material'and tools employed in and the various stages of the manufacture of the case or shell.

The shell or case is formed froma strip of paper or other pliable material having an adherent coat of paraffin of the proper thickness. I prefer to use, for this purpose a large sheet of paper a, as indicated in Figs. 3 and 3, which is ruled off by lines into subdivisions, each of which is of the size of the strip required. Upon this sheet is poured or spread melted paraffin in quantity to form when it solidifies an adherent coat orlayer b of the proper thickness. The prepared sheet is then cut up along the lines indicated into separate strips of the desired dimensions. The next step is todou'ble each strip on itself, paraffin face innermost, and to join its meeting faces, ex-

cept where the pocketis to be, formed for subsequent reception of the vaccine-charged This is conveniently done by placing the strips upon a metal surface or plate heated to such an extent as to properly soften the paraffin and then picking up each strip by a tool c,fisuch as shown in Fig. 4, the point e of which is of the shape required for the pocket. Thepoint of the tool is; pressed lightly into the softened paraflin coat about midway between the ends of the strip and is then raised, carrying with it the strip, which by hand .is doubled upon itself and pressed together around and from opposite sides of the point '0' of the tool, as

seen in Fig. 5. Thistool is in efiect a former or core, which when thus loaded is placed in varnold d, as in Fig. 6, the hinged top of which mold is then brought down upon the folded V strip, So as to press its meeting faces closely together and in intimate union around the former or core 0'. p or shell'which, asv shown in Fig. 6*, may protrude beyond the mold are trimmed'oif,

' the shell is taken from the .mold,'and the pocket in the shell far enough to take hold of The side edges of the case the shell, and the latter, held by carrier A, is

then dipped for an instant into melted paraffin,

far enough to seal the joint between the mouth of the pocket in the shelland the carrier, and the article is then thrown at onceinto ice-water in order to cool and solidify the paraffin. This completes the article, and in this completed condition it is shown in Figs. 1 and 2, in which figures B is the doubled or folded external strip of paper or pliable material, C is the inner coat of paraffin or equivalent material, A is the ivory-carrier having its Vaccinecharged point contained in the pocket formed between the meeting faces of the inner paraffin coat, and s is the seal at the mouth of the pocket, formed by dipping the shell into paraflin, as last above described. This shell removed from it readily and without injury to the vaccine charge.

Having described my invention and the manner in which the same is or may be carried into effect, what I claim herein as new, and desire to secure by Letters Patent, is

A vaccine-carrier case or shell composed of -a strip of pliable material coated with paraifin,

doubled or folded on itself,paraffin face inside, and having its meeting paraffin faces united except where the pocket is left, into which pocket is sealed the vaccine-charged point of an individual carrier, as hereinbefore set forth. 1

In testimony whereof I have hereunto set my hand this 11th day of August, 1899.
